Babies love iPhones and iPads. They learn to flick through electronic pictures of themselves on them, zooming in and out with ease, long before they utter a word. This can be a great baby distractor for desperate parents, but you don't want your mobile to end up smashed, in the loo or emailing photos of your cat to your boss.

Fisher-Price, which many will remember for its colourful toy record players, has tried to solve this by turning an iPhone into an indestructible toy. The Apptivity case safely encloses the phone.

What will an 18-month-old make of it? The initial signs are good – once the animal noises app (free from Fisher-Price) starts up, our guinea pig promptly kisses the cow on the screen. But after two minutes, the gadget is discarded as junk.

So, if you're reluctant to get your kid hooked on computer games at such a young age, worry not. It seems that dressing an iPhone up as a toy makes it infinitely less interesting to a toddler.
